Kennametal reports that its Harvi solid-carbide end mills will be included as a preferred product in Lockheed Martin’s internal machining guide. The resource, produced by Lockheed Martin Aeronautics’ Operations Technology group for internal operations and engineering, as well as global supply-chain partners, identifies the most effective parameters and processes for machining material-specific aerospace components.

“We’re honoured to be a long-time supplier to Lockheed Martin and have our Harvi III end milling portfolio featured in one of its most invaluable machining guides,” says Keith Mudge, Kennametal VP -metal cutting sales, Americas. “We work closely with customers like Lockheed Martin to solve problems and deliver the utmost accuracy in machining. The inclusion of Harvi end mills in this internal resource is a testament to our commitment in the industry and our high standard of excellence.”

Kennametal says that its Harvi solid-carbide end mill portfolio is an industry staple because of its ability to outperform other end mill tools when working on hard-to-machine aerospace materials like titanium and Inconel.A signature Kennametal brand and bestseller, Harvi end mills deliver time and cost savings in aerospace operations with fastmetal removal rates and longer tool life, reports the company.

Users experience maximum productivity from Harvi-style end mills with features like the
Harvi 1 TE’s twisted cutting edge for increased corner stability and ramping and helical interpolation operations. Further stand-out features include: proprietary relief from anti-vibration-anti-friction technology; unequal divided flutes, including some with variable helix, enabling vibration dampening and unmatched feed rates; and an innovative flute design with chip gashes to reduce cutting forces and promote more efficient chip evacuation.

In April, Kennametal launched a new end mill grade called KCSM15A and will be expanding its Harvi product lines further this autumn.
